生物结皮对植被混凝土边坡土壤团聚体分布及稳定性的影响

Shuitu Baochi Xuebao
目的为探究在边坡生态修复技术中生物结皮对土壤团聚体分布及稳定性特征的影响机制。方法以植被混凝土边坡不同生物结皮覆盖（藻结皮、混生结皮、藓结皮）土壤为研究对象，以无结皮覆盖土壤（CK）为对照，采用Le Bissonnais法分别对其不同土层（0~2、2~5 cm）土壤团聚体分布、团聚体稳定性及土壤理化属性特征进行研究。结果1）与CK相比，藻结皮、混生结皮和藓结皮覆盖土壤>0.25 mm团聚体含量（R0.25）分别增加12.53%、21.97%、30.20%（0~2 cm）和20.11%、32.00%、

蔗糖浓度对重症婴幼儿龋菌斑中变型链球菌致龋性的影响

Zhongshan Daxue xuebao. Yixue kexue ban, 2011
【目的】 探讨不同蔗糖浓度对重症婴幼儿龋(S-ECC)菌斑中变形链球菌致龋性的影响 【方法】 采集67名3 ~ 5岁S-ECC及无龋儿童牙面菌斑,获取纯化的变链菌株,接种至蔗糖浓度分别为1%5%10%及20%的PYG液体培养基,采用精密pH计测变链菌产酸能力;分光光度仪测定OD600值,评价其生长情况;蒽酮法测定水不溶性葡聚糖(WIG)的量;比浊法测定变链菌的黏附比值,对比分析变形链球菌不同临床菌株的致龋性 【结果】 随蔗糖浓度升高,S ...

三峡水库消落带不同植被类型和坡位的土壤性状分异特征

Shuitu Baochi Xuebao
目的探究三峡水库消落带植被和侵蚀对土壤性状分异的复合影响。方法选取人工恢复的狗牙根和牛鞭草群落、自然恢复的混合草本群落，针对不同坡位（上坡侵蚀、中坡过渡和下坡沉积）采集土壤分层样品，测定团聚体组成、抗剪强度和土壤基本理化性质，解析土壤性状分异特征，明确关键影响因子。结果1）人工植被恢复显著改善土壤性状。狗牙根和牛鞭草的团聚体稳定性指标（MWD、GMD）、抗剪强度指标（c、φ）、土壤有机碳（SOC）、总氮（TN）、总磷（TP）均显著大于自然草本。2）侵蚀作用导致土壤性状空间分异显著。上、中坡团聚体破碎严重，
